Aviation industry
Bost offers engineering plastics & special engineering plastics applications in aviation industry, delivering customized solutions for aircraft components with exceptional strength, heat resistance, and long-term reliability.
Key Trends & Advantages
By leveraging these materials, aerospace manufacturers enhance safety, efficiency, and design flexibility while reducing environmental impact.
Lightweighting
Specialty plastics like PEEK and PPS replace metals, reducing aircraft weight by 20–50% and improving fuel efficiency.
High-Temperature Performance
Materials like PPS and PEI withstand engine heat and harsh chemicals, ensuring reliability in critical systems.
Sustainability
Recyclable plastics (e.g., PMMA) and bio-based composites (e.g., bio-PA) are increasingly used to meet eco-friendly aviation standards.
Engineering Plastics
Engineering plastics offer a balance of mechanical strength, lightweight properties, and cost-effectiveness, making them ideal for non-critical but structurally demanding aircraft components.
Polycarbonate (PC)
➜
Applications
Cockpit windshields, cabin windows, and aircraft lighting covers.
Why
Exceptional transparency (92% light transmission), impact resistance, and heat stability up to 130°C.
Example
PC windshields in commercial airliners provide clarity while reducing weight by 50% compared to traditional glass.

Polymethyl Methacrylate (PMMA)
➜
Applications
Cockpit canopies, passenger windows, and interior partitions.
Why
High optical clarity, UV resistance, and dimensional stability.
Example
PMMA cockpit canopies in fighter jets like the F-35 allow 360° visibility while withstanding high-speed aerodynamic forces.

Nylon (PA)
➜
Applications
Fasteners, cable ties, and lightweight brackets.
Why
High tensile strength, abrasion resistance, and chemical stability.
Example
Nylon cable ties secure wiring in aircraft avionics, ensuring reliability in vibration-prone environments.

Special Engineering Plastics
Special engineering plastics excel in extreme conditions, including high temperatures, corrosive environments, and critical structural roles.
Polyether Ether Ketone (PEEK)
➜
Applications
Engine bearings, fuel system components, and composite reinforcements.
Why
Exceptional heat resistance (up to 260°C), chemical inertness, and strength-to-weight ratio.
Example
PEEK bearings in aircraft engines reduce friction and wear, extending maintenance intervals by 30%.

Polyphenylene Sulfide (PPS)
➜
Applications
Radar antennae, engine sensors, and fire-resistant interior panels.
Why
High thermal stability (up to 280°C), Flame retardant (UL94 V-0 rating), and electromagnetic transparency.
Example
PPS radar domes on commercial aircraft protect sensitive electronics while allowing unobstructed signal transmission.

Polytetrafluoroethylene (PTFE)
➜
Applications
Seals, gaskets, and non-stick coatings for fuel pipes.
Why
Low friction coefficient, chemical resistance, and temperature stability (-200°C to 260°C).
Example
PTFE-coated piston rings in aircraft engines reduce fuel consumption by minimizing mechanical resistance.

Polyetherimide (PEI)
➜
Applications
Cabin interiors, structural brackets, and electrical connectors.
Why
High strength, flame resistance, and dimensional stability at elevated temperatures.
Example
PEI cabin luggage bins in Boeing 787 Dreamliners are 20% lighter than traditional metal bins while meeting FAA fire safety standards.
